There are several reasons “stuff” is losing ground. One is that the world is aging. The median age of the global population, 23.3 years in 1985, was 31 years and climbing in 2019. While there were plenty of young consumers in Africa and South Asia, there were not so many in wealthier economies; by 2018, half the people in Japan and Germany were over age 47, and in Russia, China, and the United States the median age approached 40. Older households have had years to accumulate home furnishings and wardrobes full of clothing, and they are often disinclined to acquire more; vacation trips, restaurant meals, and medical bills are likely to figure larger in their spending than furniture and fixtures. Restaurants and hospitals also buy tables and chairs, of course, but their needs will not make up for fewer purchases by households. The share of the global population under age 15, 38 percent in the late 1960s, shrank to a mere 25 percent half a century later. With fewer young households to replace aging ones, housing, and the furnishings that go with it, is in less demand. By the European Central Bank’s count, the European Union had fewer dwellings in 2018 than two years earlier.
